Technical Field

[0001] This invention relates to the field of nuclear power engineering technology, and in particular to a continuous sphere-passing test system and method for a high-temperature reactor sphere-passing device. Background Technology

[0002] The pebble bed high-temperature gas-cooled reactor (PBT) is an advanced nuclear reactor with inherent safety, suitable for efficient power generation and high-temperature heating, and is one of the preferred reactor types in the international fourth-generation nuclear energy system. Utilizing the advantageous geometry of spherical fuel elements, the PBT can achieve refueling without reactor shutdown. According to Section 2.3.7.2 of HAD102 / 15-2021, "When an unproven design or facility is introduced, or when there is a deviation from existing engineering practice, its safety performance must be demonstrated through appropriate supporting studies, performance tests based on specific acceptance criteria, or verification through operational experience gained in other relevant applications. New designs, facilities, or practices must be fully tested before being put into service and monitored during operation to verify that the expected results have been achieved." Therefore, for newly developed non-standard equipment in the refueling system, appropriate testing equipment and methods are needed to fully verify the equipment's performance.

Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The continuous ball-passing test system for high-temperature sphere passing equipment according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the continuous ball-passing test system for high-temperature stack ball-passing equipment in this embodiment of the invention includes: ball-passing device 11, deflector 12, ball-gas separator 13, buffer 14, fan 15, and waste ball tank 16.

[0024] The sphere transfer device 11 is a newly developed specialized sphere transfer device in the pebble bed high-temperature reactor loading and unloading system. In this system, it performs functions such as single-function delivery, positioning, reversing, and helium flow obstruction of spherical fuel elements. The sphere transfer device 11 is the test object in the continuous sphere transfer test system for high-temperature reactors according to this invention, and its performance needs to be fully verified to meet the requirements of relevant regulations and guidelines. Furthermore, the test spheres used in the test are graphite spheres.

[0025] Optionally, the steering gear 12 has a test ball input end, a first test ball output end, and a waste ball output end, and the output end of the ball-passing device 11 is connected to the test ball input end via a pipeline. It can be understood that after the test ball passes through the ball-passing device 11, it sequentially enters the steering gear 12 through the output end of the ball-passing device 11 and the test ball input end of the steering gear 12. During the continuous ball-passing test, the test ball is discharged through the first test ball output end of the steering gear 12. After the test, the test ball is discharged through the waste ball output end of the steering gear 12.

[0026] Optionally, the ball-gas separator 13 has a ball-gas input end, a gas output end, and a second test ball output end, with the first test ball output end connected to the ball-gas input end via a pipeline. It is understood that during the continuous ball-passing test, the test ball in the deflector 12 sequentially enters the ball-gas separator 13 through the first test ball output end and the ball-gas input end of the deflector 12. The ball-gas separator 13 is used to separate the test ball and gas entering the separator during the test, so that the test ball is discharged through the second test ball output end of the separator 13, and the gas is discharged through the gas output end of the separator 13. Additionally, when the gas output end is blocked, the gas entering the ball-gas separator 13 can also be discharged through the second test ball output end.

[0027] Optionally, the output end of the second test ball is connected to the input end of the buffer 14 via a pipeline, and the output end of the buffer 14 is connected to the input end of the ball-passing device 11 via a pipeline. It is understood that the test ball, after being separated by the ball-gas separator 13, is discharged through the output end of the second test ball of the ball-gas separator 13 and enters the buffer 14 through its input end. The buffer 14 is used to perform the buffering function of the spherical fuel, preventing the test ball from breaking due to violent collisions during the test. After being buffered by the buffer 14, the test ball is discharged through its output end and finally returns to the ball-passing device 11 through its input end, thus completing one cycle.

[0028] Optionally, the ball-passing device 11, the deflector 12, the ball-air separator 13, and the buffer 14 together form the test ball circuit. It is understood that, as... Figure 1 As shown, the ball-passing device 11, the deflector 12, the ball-air separator 13, and the buffer 14 are all interconnected via pipelines. This allows the test ball to complete one pass through the ball-passing device 11, then sequentially pass through the deflector 12, the ball-air separator 13, and the buffer 14 via the connected pipelines before returning to the ball-passing device 11 for another pass. These four components form a test ball loop, enabling the test ball to continuously circulate within the loop, thereby verifying the various performance characteristics of the test object.

[0029] Optionally, the output end of the blower 15 is connected via a pipeline to the pipeline between the output end and the gas input end of the first test ball, and the gas output end is connected via a pipeline to the input end of the blower 15. The blower 15 is used to drive the test ball to circulate in the test ball circuit. It can be understood that after the blower 15 is started, the blower 15 promotes the gas circulation in the continuous ball-passing test system of the high-temperature reactor ball-passing equipment of this embodiment of the invention, and uses the gas flow to drive the test ball to circulate in the test ball circuit to carry out continuous ball-passing tests.

[0030] Optionally, the waste ball output end is connected to the waste ball tank 16 via a pipeline. It is understood that after the test, or when the number of consecutive ball passes through the test ball reaches a preset value, the deflector 12 is rotated, and the test ball is discharged through the waste ball output end of the deflector 12 into the waste ball tank 16. The waste ball tank 16 is used to store test balls that are periodically replaced or worn out during the test, thereby achieving the purpose of quickly replacing the test balls and improving the test efficiency of the continuous ball-passing test system of the high-temperature stack ball-passing equipment in this embodiment of the invention.

[0031] Therefore, in the continuous sphere-passing test system for high-temperature stack sphere-passing equipment of this embodiment of the invention, the sphere-passing device 11, the diverter 12, the sphere-gas separator 13, and the buffer 14 jointly establish a continuous circulation test loop for graphite spheres. The fan 15 drives the graphite spheres to conduct continuous sphere-passing tests, thereby verifying the various performance characteristics of the test object and ensuring it meets the requirements of relevant regulations and guidelines. Furthermore, by setting up the buffer 14, damage to the graphite spheres due to collisions during the test is avoided, improving the reliability of the test. The cooperation between the diverter 12 and the waste sphere container 16 also allows for rapid replacement of graphite spheres, improving test efficiency.

[0032] In some embodiments, such as Figure 1 As shown, the pipeline between the output end of the first test ball and the input end of the ball gas is the first ball-passing pipe, and the pipeline between the output end of the second test ball and the input end of the buffer 14 is the second ball-passing pipe. The first ball-passing pipe is equipped with a first test ball isolation valve 101, and the second ball-passing pipe is equipped with a second test ball isolation valve 102.

[0033] Specifically, such as Figure 1 As shown, the pipeline between the first test ball output end of the steering gear 12 and the ball gas input end of the ball gas separator 13 is the first ball passage pipe. The first test ball isolation valve 101 is provided on the first ball passage pipe. The first test ball isolation valve 101 is used to control the opening and closing of the first ball passage pipe. Graphite balls and helium can pass through the first ball passage pipe.

[0034] Specifically, such as Figure 1 As shown, the pipeline between the output end of the second test ball of the ball-gas separator 13 and the input end of the buffer 14 is a second ball-passing pipe. A second test ball isolation valve 102 is provided on the second ball-passing pipe. The second test ball isolation valve 102 is used to control the opening and closing of the second ball-passing pipe. Graphite balls and helium gas can pass through the second ball-passing pipe.

[0035] In some embodiments, such as Figure 1 As shown, the pipeline between the input end of the fan 15 and the first ball tube is the first vent pipe, and the pipeline between the gas output end and the output end of the fan 15 is the second vent pipe. The first vent pipe is equipped with a first gas isolation valve 103, and the second vent pipe is equipped with a second gas isolation valve 104.

[0036] Specifically, such as Figure 1 As shown, the connection between the first vent pipe and the first gas tube is located downstream of the first test ball isolation valve 101. Only helium gas can pass through the first vent pipe and the second vent pipe. The first gas isolation valve 103 is used to control the opening and closing of the first vent pipe, and the second gas isolation valve 104 is used to control the opening and closing of the second vent pipe.

[0037] Therefore, as Figure 1 As shown, the fan 15 drives the gas flow, and the gas flows through the first vent pipe into the first ball-passing pipe, carrying the test ball along with it into the ball-gas separator 13. Under the action of the ball-gas separator 13, most of the gas is discharged through the gas output end of the ball-gas separator 13 and flows back to the fan 15 through the second vent pipe, thus completing the gas circulation.

[0038] In some embodiments, such as Figure 1 As shown, it also includes a vacuum pump 17 and a gas storage tank 18. The vacuum pump 17 is connected to the second vent pipe via a pipeline, and a vacuum pump isolation valve 105 is provided on the pipeline between the vacuum pump 17 and the second vent pipe.

[0039] Optionally, the pumping end of vacuum pump 17 is connected to the second vent pipe via a pipeline, and the exhaust end of vacuum pump 17 is connected to the outside. Therefore, before the experiment begins, the vacuum pump isolation valve 105 is opened, and vacuum pump 17 is used to evacuate the test circuit. After the test circuit is evacuated, experimental gas (helium) is introduced into the test circuit.

[0040] In some embodiments, such as Figure 1 As shown, the gas storage tank 18 is connected to the second vent pipe via a pipeline. The pipeline between the gas storage tank 18 and the second vent pipe includes a main pipe, a first sub-pipe, and a second sub-pipe. The main pipe is connected to the second vent pipe. One end of the first sub-pipe is connected to the main pipe, and the other end of the first sub-pipe is connected to the gas storage tank 18. The first sub-pipe is equipped with a gas storage tank isolation valve 106. One end of the second sub-pipe is connected to the main pipe, and the other end of the second sub-pipe is connected to the outside. The second sub-pipe is equipped with a pressure relief valve 107.

[0041] Understandably, the gas stored in the gas storage tank 18 is the same as the coolant in the pebble bed high-temperature reactor. After the vacuum pump 17 completes the evacuation of the test circuit, the vacuum pump isolation valve 105 is closed, and the gas storage tank isolation valve 106 is opened. Test gas is then introduced into the test circuit through the gas storage tank 18 until the preset test pressure is reached, at which point the gas storage tank isolation valve 106 is closed. For example, the gas in the gas storage tank 18 is transported through the outlet of the gas storage tank 18, sequentially through the first daughter pipe and the mother pipe, to the second vent pipe, so that the gas is introduced into the test circuit.

[0042] Furthermore, after the test, the pressure relief valve 107 is opened to release pressure in the test circuit. For example, after the test, the fan 15 and the ball-passing device 11 are turned off, the pressure relief valve 107 is opened, and the gas in the test circuit is discharged to the outside through the second vent pipe, the main pipe and the second daughter pipe in sequence.

[0043] In some embodiments, such as Figure 1 As shown, it also includes a ball-filling tank 19, which is connected to the input end of the buffer 14 via a pipeline. A ball-filling tank isolation valve 109 is provided on the pipeline between the ball-filling tank 19 and the input end of the buffer 14.

[0044] Optionally, such as Figure 1 As shown, the ball-filling tank 19 has a ball-inlet end and a ball-outlet end. The ball-inlet end of the ball-filling tank 19 is connected to a first ball-filling pipe, which is equipped with a ball-replenishing isolation valve 108. The ball-replenishing isolation valve 108 is used to control the on / off state of the first ball-filling pipe. The ball-outlet end of the ball-filling tank 19 is connected to the input end of the buffer 14 via a pipeline. The ball-filling tank 19 is used to temporarily store test balls so that test balls can be added to the test circuit. The pipeline between the ball-filling tank 19 and the buffer 14 is a second ball-filling pipe, which is equipped with a ball-filling tank isolation valve 109. The ball-filling tank isolation valve 109 is used to control the on / off state of the second ball-filling pipe.

[0045] Understandably, before the test, the replenishment isolation valve 108 is opened, and multiple test graphite balls are added to the replenishment tank 19 through the first replenishment pipe, after which the replenishment isolation valve 108 is closed. Once the test begins, the replenishment tank isolation valve 109 is opened, and graphite balls are fed into the buffer 14 to the preset quantity, then the replenishment tank isolation valve 109 is closed. Thus, through the cooperation between the replenishment tank 19, the steering mechanism 12, and the waste ball tank 16, when it is necessary to replace the graphite balls in the test circuit, the steering mechanism 12 is rotated to discharge the graphite balls to be replaced into the waste ball tank 16. Then, the steering mechanism 12 is rotated back, the replenishment tank isolation valve 109 is opened, and new graphite balls are replenished into the test circuit, thereby achieving the purpose of quickly replacing the graphite balls in the test circuit.

[0046] Specifically, such as Figure 1 As shown, the ball-filling tank 19 is connected to the second ball-passing pipe via the second ball-filling pipe, and the connection between the second ball-filling pipe and the second ball-passing pipe is located downstream of the second test ball isolation valve 102.

[0047] In some embodiments, such as Figure 1 As shown, it also includes a dust adder 20, which is connected to the input end of the ball passing device 11 via a pipeline. An adder isolation valve 111 is provided on the pipeline between the dust adder 20 and the input end of the ball passing device 11.

[0048] Optionally, such as Figure 1As shown, the dust additive 20 has a dust inlet and a dust outlet. The dust inlet of the dust additive 20 is connected to a first dust pipe, and a dust filling isolation valve 110 is provided on the first dust pipe to control the opening and closing of the first dust pipe. The dust outlet of the dust additive 20 is connected to the input end of the ball-passing device 11 via a pipeline. The dust additive 20 is equipped with multiple sets of dust storage tubes, which store a preset amount of graphite dust. Graphite dust can be added to the ball-passing device 11 periodically and quantitatively according to experimental requirements to simulate the actual operating conditions of the test object.

[0049] Furthermore, such as Figure 1 As shown, the pipeline between the dust adder 20 and the ball-passing device 11 is the second dust pipe, which is equipped with an adder isolation valve 111. The adder isolation valve 111 is used to control the opening and closing of the second dust pipe. Understandably, before the test, the dust adder isolation valve 110 is opened, and a certain amount of graphite dust is added to the dust adder 20 through the first dust pipe, after which the dust adder isolation valve 110 is closed. After the test begins, the adder isolation valve 111 is opened, and graphite dust is periodically and quantitatively added to the ball-passing device 11. Thus, by setting up the dust adder 20, various harsh dust operating environments in the field are simulated, and the impact of graphite dust on the operation of the test equipment is explored.

[0050] In some embodiments, such as Figure 1 As shown, it also includes a dust filter 21. The ball-passing device 11 has a dust discharge end, which is connected to the input end of the dust filter 21 via a pipeline. The output end of the dust filter 21 is connected to the second vent pipe via a pipeline. A first filter isolation valve 112 is provided on the pipeline between the dust discharge end and the input end of the dust filter 21, and a second filter isolation valve 113 is provided on the pipeline between the output end of the dust filter 21 and the second vent pipe.

[0051] Understandably, during a normal ball-passing test, the first test ball isolation valve 101, the second test ball isolation valve 102, the first gas isolation valve 103, and the second gas isolation valve 104 are all in the open state, while the first filter isolation valve 112 and the second filter isolation valve 113 are in the closed state. The gas circuit formed at this time is: fan 15 - ball-gas separator 13 - fan 15. That is, gas is discharged from the gas output end of the ball-gas separator 13.

[0052] When cleaning dust from the test circuit, close the first test ball isolation valve 101 and the second gas isolation valve 104, and open the first filter isolation valve 112 and the second filter isolation valve 113. The gas circuit at this time is: fan 15 - ball-gas separator 13 - buffer 14 - ball-passing device 11 - dust filter 21 - fan 15. That is, gas is discharged from the output end of the second test ball of the ball-gas separator 13, blowing graphite powder to the dust filter 21 for cleaning and collection. Thus, by setting up the dust filter 21, excess graphite dust in the test system can be collected and cleaned periodically.

[0053] In some embodiments, such as Figure 1 As shown, the dust discharge end is also connected to the first vent pipe via a pipeline, and a backflush isolation valve 114 is installed on the pipeline between the dust discharge end and the first vent pipe.

[0054] Specifically, such as Figure 1 As shown, the pipe connecting the dust discharge end of the ball passing device 11 and the first vent pipe is a backflush pipe. The connection between the backflush pipe and the first vent pipe is located upstream of the first gas isolation valve 103, and a backflush isolation valve 114 is provided on the backflush pipe.

[0055] Understandably, when the ball-passing device 11 malfunctions and becomes stuck, the first gas isolation valve 103 is closed and the backflush isolation valve 114 is opened, so that the gas is blown in the opposite direction to the ball-passing device 11, thereby relieving the stuck phenomenon.

[0056] In some embodiments, such as Figure 1 As shown, a heating band 22 is provided on the outer shell of the ball-passing device 11. It can be understood that the heating band 22 covers the outer shell of the ball-passing device 11 and is used to heat the ball-passing device 11 to simulate the ambient temperature of actual working conditions.

[0057] The following describes the continuous ball-passing test method of the high-temperature ball-passing device according to an embodiment of the present invention.

[0058] The continuous pounding test method for a high-temperature reactor pounding device according to embodiments of the present invention is used in the continuous pounding test system for a high-temperature reactor pounding device in the above embodiments. The method includes:

[0059] Add multiple test balls to the ball-passing device 11.

[0060] Start the drive mechanism of the fan 15 and the ball passing device 11 so that the test ball passes through the deflector 12, the ball air separator 13 and the buffer 14 in sequence, and then returns to the ball passing device 11 to perform continuous cyclic ball passing.

[0061] After the preset number of ball cycles is completed, rotate the steering mechanism 12 to discharge the worn test balls into the waste ball tank 16 for storage.

[0062] Specifically, before the test, ensure that all isolation valves in the continuous ball passing test system of the entire high-temperature reactor ball passing equipment are in the closed state.

[0063] Experimental preparation:

[0064] S1: Open the ball replenishment isolation valve 108, add multiple test graphite balls to the ball replenishment tank 19, and then close the ball replenishment isolation valve 108. Open the dust addition isolation valve 110, add a certain amount of graphite dust to the dust adder 20, and then close the dust addition isolation valve 110.

[0065] S2: After opening the first test ball isolation valve 101, the second test ball isolation valve 102, the first gas isolation valve 103, and the second gas isolation valve 104, open the vacuum pump isolation valve 105 and start the vacuum pump 17 to evacuate the test circuit. After evacuation is complete, close the vacuum pump isolation valve 105.

[0066] S3: Open the gas storage tank isolation valve 106, and charge the test gas into the test circuit through the gas storage tank 18 until the preset test pressure is reached, and then close the gas storage tank isolation valve 106.

[0067] Experiment Implementation:

[0068] S1: Open the ball filling tank isolation valve 109, add a preset number of graphite balls to the ball passing device 11, and then close the ball filling tank isolation valve 109.

[0069] S2: Activate the heating belt 22 to heat the test object (ball-passing device 11) to the preset temperature.

[0070] S3: Start the drive mechanism of the fan 15 and the ball-passing device 11.

[0071] S4: Open the adder isolation valve 111, add a preset amount of graphite dust to the ball-passing device 11, and then close the adder isolation valve 111.

[0072] S5: A continuous circulation loop for graphite balls is established by the blower 15. After the preset number of ball cycles is completed, the steering gear 12 is rotated to open the waste ball tank isolation valve 115 so that the worn graphite balls can be discharged to the waste ball tank 16 for storage.

[0073] S6: Close the first test ball isolation valve 101 and the second gas isolation valve 104, open the first filter isolation valve 112 and the second filter isolation valve 113, purge the dust in the test circuit, and use the dust filter 21 to clean and collect the graphite powder.

[0074] S7: Repeat steps S1-S6 to fully verify the performance of the test object under various operating conditions.

[0075] In addition, when the ball-passing device 11 malfunctions during the test, the first gas isolation valve 103 is closed and the backflush isolation valve 114 is opened to allow the gas to purge and unblock in the reverse direction.

[0076] After the experiment:

[0077] Turn off the drive mechanism of the fan 15 and the ball-passing device 11, and open the pressure relief valve 107 to relieve pressure on the test circuit.

[0078] Therefore, the continuous sphere-passing test method for the high-temperature sphere-passing device of this invention establishes a continuous cyclic test loop for graphite spheres, which can fully verify the performance of the sphere-passing device 11 under various operating conditions.
